The Nios CPU Component for SOPC Builder

Hi,

Can someone please tell me where I can download the nios cpu component for sopc builder for the nios development kit, cyclone edition. I am a university project student and for some reason the university has removed the accompanying CD that contains all the required files from the kit.

It seems that NIOS I and Cyclone I technology are very out of date and I am struggling to find any good documentation or help on this, even at altera.com/devkits. I would greatly appreciate it if someone can provide me with a link to download the component, or, if someone can provide me with a good reference for this board so that I can develop my own SOPC design.

Thanks in advance.:)
